HDS03.1-W100N-HT05-01-FW
The HDS03.1-W100N-HT05-01-FW is a drive controller built by Bosch Rexroth Indramat for the HDS Drive Controllers series. Integrated in a multi-axis drive rack, it converts digital setpoints into controlled current and voltage for servo or spindle motors. By supervising acceleration, velocity, and position loops, the unit coordinates machinery such as packaging stations, material-handling gantries, and CNC subsystems on automated production lines. It mounts beside HMS and HDC modules on a common power bus so several axes can share one supply section. This arrangement lets the controller act as the regulation stage for an individual axis while power distribution remains centralized in the cabinet.
Motion commands reach the module through the SERCOS fiber-optic ring, allowing deterministic high-speed exchange with the central PLC. The power stage is rated for a continuous output of 100 A, making it suitable for medium- to high-torque motors in coordinated multi-axis arrangements. Thermal management relies on a built-in internal air blower, which directs air across the heat sink to keep semiconductor temperatures within a safe operating range. The controller belongs to the DIAX04 family and is part of Line 03, matching the layout used by related rack modules. That combination supports coordinated speed and torque control when several drives operate in the same machine section.
The unit is Version 1, indicating the first design release of the logic and power boards. The front command interface connectors are placed on the panel for direct access to short optical jumpers, which helps keep cable routing clear inside the rack. Their front-panel position also reduces the need to route optical leads behind neighboring modules. Air is guided through the cooling duct so flow remains directed across internal surfaces during operation. The module is intended for use as the regulation stage in a shared drive enclosure where multiple axes are installed side by side.
